The BIOTEX project aims at developing dedicated biochemical-sensing techniques compatible with integration into textile. This goal represents a complete breakthrough, which allows for the first time the monitoring of body fluids via sensors distributed on a textile substrate and performing biochemical measurements. BIOTEX is addressing the sensing part and its electrical or optical connection to a signal processor. The approach aims at developing sensing patches, adapted to different targeted body fluids and biological species to be monitored, where the textile itself is the sensor. The extension to whole garment and the integration with physiological monitors is part of the roadmap of the consortium.
